Work

Selected work from our own bench: digital, power, communications and motors.

Everything here comes out of one workshop: the lab where it's built.

3D render of the B156 Just Screw It adapter: a box header on top, two screws and the alignment pins below
FIG. 8
3D render of the B156 Just Screw It adapter from the pogo-pin side, with six pogo pins between the alignment pins

Just Screw It (B156)

  • A PCB connector at no part cost: tiny screws tapped straight into the board hold it
  • Two alignment pins set the position and the height gap the pogo pins need
  • B156 carries a 6-pin SWD connection on pogo pins
  • First use: the B200 rePort board
